Abstract

The utility model relates to a ballast turnout sleeper for a line for passenger transportation, which comprises a turnout sleeper concrete body, prestressed steel wires, a sleeve pipe and electricity screw nuts, wherein the prestressed steel wires, the sleeve pipe and the electricity screw nuts are pre-buried inside the turnout sleeper concrete body, the turnout sleeper concrete body is in a full-length integral type, the cross section of the turnout sleeper concrete body is in a trapezoid shape with the smaller upper part and the larger lower part, the prestressed steel wires are buried along the turnout sleeper concrete body in a full-length way and are distributed in a rectangular shape at intervals on the cross section of the turnout sleeper concrete body, first hoop ribs and second hoop ribs integrally surround the periphery of the prestressed steel wires, the first hoop ribs are distributed in the length direction of the turnout sleeper concrete body at intervals, and the second hoop ribs are arranged at both ends of the turnout sleeper concrete body. The ballast turnout sleeper has the advantages that the intensity of the turnout sleeper concrete body per se is improved through the prestressed steel wires, the end part corner falling can be prevented through the second hoop ribs, the installation intensity of the sleeve pipe can be ensured through spiral ribs arranged around the sleeve pipe, the electricity screw nuts pre-buried at both ends of the turnout sleeper concrete body can be used during preserved hole passage installation, the appearance dimension design of the turnout sleeper concrete body is reasonable, the structural bearing capability is enhanced, and the requirement of high speed of train lines for passenger transportation can be met.

Description

Line for Passenger Transportation has tiny fragments of stone, coal, etc. switch tie

Technical field

The utility model relates to a kind of PRESTRESSED CONCRETE TURNOUT SLEEPERS.

Background technology

Line for Passenger Transportation has tiny fragments of stone, coal, etc. switch tie technical sophistication, standard height, requires sternly.Impact force and frictional force when reducing the Line for Passenger Transportation train operation improve the stationarity of train operation, adapt to the needs of train high-speed cruising, and Line for Passenger Transportation has tiny fragments of stone, coal, etc. switch tie appearance and size precision prescribed height, and bearing capacity and anti-fatigue ability are strong.The scope of application that tiny fragments of stone, coal, etc. switch tie is arranged of different size specification has very big difference.And have the structure design of tiny fragments of stone, coal, etc. switch tie comparatively simple, concrete later strength, bearing capacity and fatigue strength deficiency.The design of the appearance and size of switch tie, compressor wire and built-in fitting all needs further to improve, and improves constantly requirement to the switch tie bearing capacity to adapt to Line for Passenger Transportation train operation speed per hour.

The utility model content

The utility model provides a kind of Line for Passenger Transportation that tiny fragments of stone, coal, etc. switch tie is arranged, and solve existing Line for Passenger Transportation has tiny fragments of stone, coal, etc. switch tie supporting capacity deficiency, stable low, the technical problem that application life is short.

The technical scheme that its technical problem that solves the utility model adopts is:

This Line for Passenger Transportation has tiny fragments of stone, coal, etc. switch tie, comprise the switch tie concrete bodies, and the compressor wire, sleeve pipe and the electric affair nut that are embedded in switch tie concrete bodies inside, described switch tie concrete bodies is elongated monolithic, shape of cross section is up-small and down-big trapezoidal, described compressor wire is buried underground along the switch tie concrete bodies is elongated, and it is rectangular spaced apart on the cross section of switch tie concrete bodies, be wound with stirrup I and stirrup II in the peripheral integral loop of compressor wire, to spaced apart, stirrup II is arranged at the both ends of switch tie concrete bodies to stirrup I along switch tie concrete bodies length;

Described sleeve pipe is the cylindrical structural of following end closure, and the sleeve pipe peripheral ring is wound with spiral bar, and sleeve pipe is spaced apart along switch tie concrete bodies end face center line;

Described electric affair nut is distributed in the both ends of switch tie concrete bodies end face.

Described compressor wire is distributed with totally 14 of four rows and four columns on the cross section of switch tie concrete bodies.

Described electric affair nut respectively is distributed with three at the both ends of switch tie concrete bodies end face.

The length of described switch tie concrete bodies is 2.45m～4.8m.

The height of described switch tie concrete bodies is 220mm, and the top margin width is 260mm, and the base width is 300mm.

The beneficial effects of the utility model are as follows:

The utility model is embedded with four rows and four columns totally 14 steel wires in switch tie concrete bodies inside, and is equipped with stirrup in the steel wire outer periphery, has improved the intensity of switch tie concrete bodies own.Wherein stirrup II is arranged at switch tie concrete bodies two ends, can prevent the end arrisdefect.The spiral bar that is provided with around the sleeve pipe can guarantee the installation strength of sleeve pipe.The pre-buried electricity affair nut in switch tie concrete bodies two ends can use when reserving hole channel is installed.Switch tie concrete bodies appearance and size of the present utility model is reasonable in design, structural bearing capacity strengthens, long service life, can satisfy the requirement of the high speed per hour of Line for Passenger Transportation train.
